Would any of you happen to have a TIGCC/C string input routine that lets you set the X and Y coordinates of the prompt (kind of like MoveTo(x,y) and then using getsn()) and works when interrupts 1, 5, and 6 are redirected?

No, not really, but I adapted the TIGCC Docu example to fit most of your needs. However, my code requires AUTO_INT_1, but are you sure you can't enable this interrupt for a short time? Otherwise you would have to write a getKey replacement working without AUTO_INT_1.
| c: | // ----------------------------------------------------------------- // // checks for keypresses and turns the calc of if APD expired // originally taken from TICT sources // ----------------------------------------------------------------- // short getKey(void) { void *kbq = kbd_queue(); unsigned short key; // restart the APD timer now OSTimerRestart(APD_TIMER); // get an input while (OSdequeue(&key, kbq)) { // check if it is necessary to turn the calc off if (OSTimerExpired(APD_TIMER)) { off(); OSTimerRestart(APD_TIMER); } } // erase the status line ST_eraseHelp(); // allow key repetition return key & 0xF7FF; } // Custom String Input Function void InputStr(char *buffer, unsigned short maxlen, short x, short y) { SCR_STATE ss; short key; unsigned short i = 0; buffer[0] = 0; MoveTo(x,y); SaveScrState(&ss); do { MoveTo(ss.CurX, ss.CurY); // Note that two spaces are required only if the F_4x6 font is used printf("%s_ ", buffer); key = getKey(); if (key >= ' ' && key <= '~' && i < maxlen) buffer[i++] = key; else if (key == KEY_BACKSPACE && i) i--; buffer[i] = 0; } while (key != KEY_ENTER); } // Main Function void _main(void) { char s[21]; // NOTE: <s> must be 21 bytes long (zero byte at the end of the string! this is a bug in the tigcc docu! clrscr(); InputStr(s, 20, 10, 10); printf("\n%s", s); ngetchx(); }
